A pressurized water toy providing a pressure actuated pulsator for shooting water in consecutive pulses. The pressure actuated pulsator includes expansible inlet and outlet tubing, a reservoir for the temporary retention of water, and a sphere-shaped obturator for temporarily blocking the flow of water through the outlet tubing. Flow of pressurized water into the expansible tubing expands and elongates the tubing and forces a seal to be formed by biasing the sphere-shaped obturator against a first end of the outlet tubing compressing a spring. A buildup of pressure behind the obturator causes the expansible tubing to expand and permit passage of the pressurized water around the obturator and into and through the nozzle. When the pressure behind the obturator drops below a certain level, the obturator again blocks the orifice into the outlet tubing causing a buildup of pressure there behind and the cycling of pulse of water flow continues.
